9 of 9 conditions
Residuals of Traumatic Brain Injury (TBI)
TBI results from head trauma and can cause lasting issues with memory, mood, sleep, and decision-making.

Read the condition guidePreview the guide
Evidence covered in the guide
- Consistent reports of tinnitus in VA exams
- History of military noise exposure (e.g., flight line, artillery)
- C&P exam confirmation
Lumbosacral or Cervical Strain
A strain or sprain of the muscles and ligaments supporting the neck or lower back, causing pain, stiffness, and reduced range of motion — often from lifting, impact, or repetitive strain during service.
Read the condition guidePreview the guide
Evidence covered in the guide
- C&P or orthopedic exam showing measured loss of range of motion, muscle spasm, or guarding
- Service treatment records documenting the in-service injury, incident, or repetitive strain
- Buddy statements or personnel records corroborating the in-service event (e.g., heavy lifting, vehicle accident, parachute jumps)
Degenerative Arthritis of the Spine
Wear and tear in the spine causing stiffness, pain, or nerve issues.

Evidence covered in the guide
- Range of motion tests from VA or ortho
- MRI or X-ray showing degenerative disc disease
- Doctor notes on back pain frequency
Knee, Other Impairment of
This diagnostic code covers knee instability — the knee buckling, giving out, or shifting out of place — separately from pain or arthritis. Since the 2021 rewrite it rates two named things: recurrent subluxation or instability after a ligament sprain or tear, and instability of the kneecap (the patellofemoral complex) after surgical repair. The tier you land on depends less on how bad the instability feels than on what a medical provider has prescribed for it — a brace, a walking aid, both, or neither.
Read the condition guidePreview the guide
Evidence covered in the guide
- The prescription itself — the note or order from a medical provider prescribing a brace, cane, crutches, or a walker for walking. Since 2021 this is the single fact that separates the three tiers, and buying a brace over the counter is not the same thing.
- An orthopedic evaluation documenting persistent instability with stability testing (Lachman, anterior drawer, pivot shift), and stating whether a ligament tear is complete or incomplete.
- Operative reports where a ligament or the patellofemoral complex was repaired, plus follow-up notes on whether the repair held — a failed repair rates higher than a successful one on the same prescription.
Post-Traumatic Stress Disorder (PTSD)
PTSD is a mental health issue caused by a traumatic event, leading to flashbacks, anxiety, or nightmares.
Read the condition guidePreview the guide
Evidence covered in the guide
- Formal PTSD diagnosis from a VA or private psychiatrist
- C&P exam results showing PTSD symptoms
- Buddy statements confirming trauma or symptoms
Glaucoma
Glaucoma is a group of eye diseases in which pressure inside the eye damages the optic nerve, narrowing the field of vision over time. The VA schedule codes it in two forms — open-angle glaucoma (DC 6013) and angle-closure glaucoma (DC 6012) — and gives them word-for-word identical rating instructions.
Read the condition guidePreview the guide
Evidence covered in the guide
- Optometry records tracking eye pressure and vision over time.
- Visual field tests measuring the extent of any vision loss.
- Ophthalmologist reports documenting the diagnosis and treatment plan.
Bursitis
Bursitis is inflammation of a bursa — one of the fluid-filled sacs that cushion tendons and muscles where they pass over bone — most often at the shoulder, hip, elbow or knee, causing pain and painful, restricted motion. DC 5019 has no percentages of its own: it is rated as degenerative arthritis, on limitation of motion of the affected joint.
Read the condition guidePreview the guide
Evidence covered in the guide
- Goniometer range-of-motion measurements, in degrees, for the affected joint — this is the only thing DC 5019 rates, and a compensable evaluation depends on comparing it against that joint's own diagnostic code.
- Examination findings recording objective painful motion, swelling or muscle spasm, which is the confirmation DC 5003 requires before the per-joint 10 percent can be assigned.
- Imaging (ultrasound or MRI) showing bursal thickening or effusion, and any aspiration or injection records, which establish the diagnosis.
Muscle Group VI (Elbow Extensors)
Injury to the muscles that straighten the elbow — the triceps and the anconeus.
Read the condition guidePreview the guide
Evidence covered in the guide
- An orthopedic specialist's report documenting the muscle injury.
- Functional use testing assessing strength and coordination.
